Speed: Distance travelled in unit time (m/s). Frequency: Number of waves that pass a point per second (Hz). Wavelength: Distance between matching points on the wave (m). Longitudinal: Vibration parallel to direction of travel. Transverse: Vibration at right angle to direction of travel. VideoThe sound is created by the vibration on the surface of an object, in this case drums, strings and wind instruments. The vibration releases invisible waves that go back and foward producing new waves when the air particles collide with each other, this way transmiting the sound. Frequency: is the total number of times per second that an air molecule moves back and foward. The oscilloscope is an instrument used to messure the sound waves. They are reflected on a oscillogram so you can observe the amplitud and frequency of the waves. The condensation of the air molecules move the line up in the oscillogram.
